Hi, I'm looking to emulate a Tascam portastudio 488 for a project, the idea is to copy its workflow and make a fxchain to emulate it the most accurately. The only part i'm kinda stuck is with Chow Tape, I made a little preset trying to emulate portastudio's sound but keep feeling i'm not so close. Any idea on how to?

At the same time i thought in having multiple fxchains to emulate different tape machines, so i ask you. Do you have any emulation presets you want to share? Or how can anyone make mostly accurate presets?
